Should Handheld multimeters have color LCD displays?

scottiebabe
scottiebabe over 2 years ago

As I am waiting for my OWON HDS242 to come in the mail, I thought I might ask other members how they feel about a handheld multimeter having a power hungry color LCD display.

The product webpage suggests a battery life of 3-6 hours. https://www.owon.com.hk/products_owon_hds200_series_digital_oscilloscope 

Even more interesting/exciting is the batteries can be recharged with a USB-C cable.

Based on Kerry Wong's teardown: http://www.kerrywong.com/2021/09/18/teardown-of-an-owon-hds272s-3-in-1-handheld-oscilloscope-dmm-awg-compared-with-hantek-2d72/ the multimeter functionality is galvanically isolated from the usb connector.

What do you think?

First time trying the poll feature, hopefully I didn't goof it!

Based on Kerry's notes the meter also has the bones of a real oscilloscope (ADC, FPGA, Sample memory, etc..) How performant is oscilloscope it? I don't know yet.... But I am intrigued!

Update: The scopemeter arrived!

Indoors the color LCD looks awesome! For me my multimeter ends up either sitting flat on my desk on in my lap and in both those cases the display is 10x easier to read than a segment LCD without a backlight.

Outdoors with direct sunlight the segment LCD is easier to read than the color LCD.

In the shade outdoors, I think both display technologies are equally legible.

    So.... I'd say, "yes," but, I'd rather have a higher-quality monochrome than a lower-quality color. That said if I can slightly flex, a company called Kaitweets sent me one of their meters. These are…

    No matter how you try to 'colour the situation' up front, in reality something is still likely to be broken... Slight smile

    Still, I guess you could always colour coordinate... Slight smile

    Not sure what colour would add unless it could, for example, plot multiple different signals together, maybe a reference signal from memory and then a measured signal.  It will be interesting to see what you make of it.

    I put my money on this:
    "in a few years, we will not understand how we could ever live without colour DMMs,
    and these DMMs will have a longer battery life than the ones we have now."

    You perhaps could use it to highlight if a reading was within allowable limits or not. Might be useful for someone doing a lot of repeated testing.

    Color is cool and can be useful, but I put a heavy weight on battery life.

    For a meter that sees frequent use, I would give up some functionality to get a big improvement in battery life.

    I would actually like to see low power displays on some phones.

    I have an e-ink e-reader that lasts orders of magnitude longer on a charge than my color Kindle. Guess which one I use. Relaxed

    I have an LCD DMM that is over 38 years old - It was my main meter for about 15 years, I have never replaced the AA batteries. It still works on the original alkaline batteries.

    Also since I am often video recording meters, I do not want raster flicker or multiplexing flicker in my videos.

    I think we'll see more meters with a PC connection (USB or BT). You can then capture measurements off the screen.

    Louis Rossman uses this technique: software that overlays the measurements on top of the screen:

    Yes for an oscilloscope color is definitely essential. I suppose the world has made it this far with handheld mulitermeters being mostly monochromatic. I am really interested to see if the viewing angle of the display is like a smartphone, essential +- 90.

    Old habits die hard I suppose. I had once thought 9V batteries in meters was silly. After buying rechargeable 9V batteries, I changed my mind. In the event the battery gets low I just charge it with minigrabbers and a bench supply. Knowing that the unit has a rechargeable battery I will leave it running (sometimes backlight too!) without worrying about saving battery life. I know I will just charge it when the battery gets low.

    I'm so used to powering/charging devices with USB I don't think it will phase me, but I won't know until I try it!
